    Gray and white matter alterations in Obsessive-Compulsive Personality Disorder: a data fusion machine learning approach by Lorenzo Arena, Wenceslao Peñate, Wenceslao Peñate, Francisco Rivero, Rosario J. Marrero, Rosario J. Marrero, Teresa Olivares, Alessandro Scarano, Ascensión Fumero, Ascensión Fumero, Alessandro Grecucci

    Published 2025-05-01
    “…One intriguing hypothesis is that regions ascribed to the Default Mode Network are involved in OCPD, similar to what has been shown for OCD and other anxiety disorders.MethodsTo test this hypothesis, the gray and white matter images of 30 individuals diagnosed with OCPD (73% female, mean age=29.300), and 34 non-OCPD controls (82% female, mean age = 25.599) were analyzed for the first time with a data fusion unsupervised machine learning method known as Parallel Independent Component Analysis (pICA) to detect the joint contribution of these modalities to the OCPD diagnosis.ResultsResults indicated that two gray matter networks (GM-05 and GM-23) and one white matter network (WM-25) differed between the OCPD and the control group. …”
